GUI slider for manual control doesn't have any values, just UI slider. For my eye, logical 50% brightness looks like 80 out of 100%. Corresponding values via terminal are below: evgeny@egramm16:~$ cat /sys/class/leds/kbd_backlight/brightness 0 evgeny@egramm16:~$ cat /sys/class/leds/kbd_backlight/brightness 127 evgeny@egramm16:~$ cat /sys/class/leds/kbd_backlight/brightness 255 --=20 You may reply to this email to add a comment.
